What is Green Diamond mean?

The Green Diamond was a streamlined passenger train operated by the Illinois Central Railroad between Chicago, Illinois and St. Louis, Missouri. It operated from 1936 until 1968. It was the Illinois Central's first streamliner. Initially it operated with Illinois Central 121, the last of the 1930s fixed-consist articulated streamliners built in the United States.
